Variable $before doesn’t appear in any GraphQl query

I want to create headless wordpress with next.js. But when I want to create pagination I can not use before state in my query. I have added picture and my query below, my variables works fine. I have checked them

const query = `
  query allPosts($after: String = "", $before: String = "", $first: Int) {
    posts(first: $first, after: $after, before : $before) {
      edges {
        node {
          author {
            node {
              name
            }
          }
          id
          title
          date
          excerpt
          featuredImage {
            node {
              sourceUrl
              title
            }
          }
          uri
          slug
          categories {
            nodes {
              uri
              count
              databaseId
              id
              name
              parent {
                node {
                  uri
                  count
                  databaseId
                  id
                  name
                }
              }
            }
          }
        }
      }
      pageInfo {
        hasNextPage
        hasPreviousPage
        endCursor
        startCursor
      }
    }
  }`;
